High-frequency treatment device for endoscopic spinal surgery

Abstract

The present invention relates to a high-frequency treatment device for spinal endoscopic surgery, the device including: a casing; an insert rod extending in a longitudinal direction of the casing; and an electrode tip formed at a front end of the insert rod to apply heat to a treatment part. Accordingly, it is possible to not only immediately remove in-body soft tissues or ligaments that interfere with the visual field of an endoscope in an operation, but quickly stop bleeding, and it is also possible to discharge contaminated substances with a saline solution from a treatment part, thereby allowing an accurate and effective operation.

What is claimed is: 
     
       1. A high-frequency treatment device for spinal endoscopic surgery, the high-frequency treatment device comprising:
 a casing; 
 an insert rod extending in a longitudinal direction of the casing; and 
 an electrode tip formed at a front end of the insert rod to apply heat to a treatment part, 
 wherein the electrode tip includes: 
 a body fitted in the front end of the insert rod and having a passage that communicates with the insert rod, and a seat on a first side of the body; and 
 a heat generator formed in the seat, the heat generator including a plurality of protrusions for preventing the heat generator and tissue of a human body from sticking to each other, and a plurality of holes that communicate with the passage of the body, 
 wherein at least one of the plurality of holes is provided closer to the front end of the insert rod than any of the plurality of protrusions, 
 wherein a shield for isolating the heat generator from a human tissue is further formed on a second side of the body, 
 wherein a recess portion and a rim portion are provided on top of the shield, the recess portion being surrounded by the rim portion, heights of the rim and recess portion being lower than the seat, 
 wherein the recess portion has a flat bottom that is lower than the rim portion. 
 
     
     
       2. The high-frequency treatment device of  claim 1 , wherein a seat for accommodating the heat generator is formed on the first side of the body, and
 the heat generator is disposed inside the seat and is operated with the protrusions exposed outside. 
 
     
     
       3. The high-frequency treatment device of  claim 1 , further comprising a discharge tube for discharging a saline solution to outside a human body through the holes, the passage, and the insert rod, wherein the saline solution has been injected to a treatment part in the human body. 
     
     
       4. The high-frequency treatment device of  claim 1 , wherein the casing has a trigger at a side to operate the electrode tip. 
     
     
       5. The high-frequency treatment device of  claim 1 , wherein the insert rod is formed in a hollow pipe coated with an insulating material on an outer side thereof. 
     
     
       6. The high-frequency treatment device of  claim 1 , wherein a high-frequency output unit operated to output high frequency waves by power supplied from the outside is disposed in the casing and energy generated by the high-frequency output unit is transmitted to the electrode tip. 
     
     
       7. The high-frequency treatment device of  claim 6 , wherein a switch unit operating the high-frequency output unit is further disposed in the casing, and
 the high-frequency treatment device further comprises: 
 a sensing unit determining suitability of temperature of tissues in a treatment part; and 
 a controller turning on and off the switch unit in response to information sensed by the sensing unit, 
 wherein the sensing unit and the controller are installed with the electrode tip. 
 
     
     
       8. The high-frequency treatment device of  claim 7 , wherein the sensing unit includes an in-body sensor inserted into a human body in an operation. 
     
     
       9. The high-frequency treatment device of  claim 8 , wherein the sensing unit includes an out-body sensor fastened on a finger or a toe of a patient to sense a nerve reaction of the finger or the toe.
